Problems unlocking bootloader

Hey guys, I'm having a problem rooting my GS3. I believe the problem is in unlocking the bootloader. I've watched a few of the video tutorials and go thru the proceedure to unlock, flash recovery and root the phone using ODIN 3.07. Everything runs smoothly with no apparent errors. But when I boot into recovery and flash a custom ROM, I get the infamous yellow triangle and a message telling me the software is not authorized by verizon and I need to return the phone to a verizon store. I'm able to get out of the softbrick using ODIN to flash a stock ROM again but I can't figure out what's going on and why I can't get the bootloader unlocked. Is there a utility to tell if the bootloader is unlocked or another way to check? At least on that doesn't involve softbricking the device. BTW, the phone is on the latest 4.1.2 jellybean update. Let me know if you guys need any other specific info on the phone and I'll post it. Any help is greatly appreciated!!!

What image are you flashing to root your phone? Most of them don't include the unlocked boot loader (they only root). If you're stock, rooted, the easiest way to unlock the bootloader is to download the ez unlock app from the play store (make sure it's for verizon gs3)

I can't remember the files off the top of my head but I'll look into them and re post when I get them.
So if I understood your post correctly, I should be able to root my phone like I've been doing and then download the app you mentioned to unlock the bootloader. Correct?

Basically. what I did was root, then bootloader, then custom recovery (I'm still on 4.1.1).Though I found the image that had the unlocked bootloader already included if you have 4.1.1 or 4.1.2.

Be sure to read directions, check your md5's before flashing, and only flash Odin files in the pda slot.
If you followed that guide above before and it didn't work, just try to unlock the bootloader with the app instead.

Hmm.....still no luck. Also, I'm not sure what app to download to unlock the bootloader.
Here's a link to the video I followed. I used the files mentioned in it and the links to them on the site. As far as I can tell, it all looks good.

I believe this is the app to unlock bootloader
https://play.google.com/store/apps/details?id=com.mmmeff.ez.unlock

did the bootloader unlock app get pulled from the play store? I just searched and couldn't find it.
Here's the original thread by the dev with download links. Not sure if the links are still active though...
http://forum.xda-developers.com/showthread.php?t=1839791

Here's a little more info: I ran rootchecker and it came back that I had root access granted and busybox installed. Under build info it list the bootloader as I535VRALEC. Under fingerprint it says: 4.1.2/JZO54K/I535VRBMA2. Is it OK that these two don't match?

Yes it's fine. Once youre set (rooted, unlocked, custom recovery), you can restore the original boot chain if you want. Don't have to but if you do you can find the files in the thread I linked to in post #4

Flash a custom recovery such as TWRP and use it to install a SuperSU zip (preferrably the latest version.) The exact details can be found in the forum somewhere.

Is there anyway to do this without unlocking the boot loader?
It won't flash the recovery when I try and the guide I found to unlock the boulder requires going to a site to get an unlock code and that site is down.

I don't think so. You can't install a custom recovery without unlocking the bootloader, and without a custom recovery you can't flash to the system partition, which you need to do with most "regular" root apps such as SuperSU. Since KingRoot doesn't seem to work, it seems you're out of luck.
I remember that it took me quite an effort to get my bootloader unlocked, I had to do a ton of searching in these and other forums, but in the end I found a way that worked. Maybe you just need to dig a little deeper

Easiest would be to ODIN to PB1, root that, then use the SafeStrap from that load to run any PB1 rom or upgrade to PD1
To ODIN and root PB1 follow http://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370
ODIN to PB1 is found in the section "Prepare your phone for root"
Root is in the first part of the OP, I did from the "very important" until line 5 (skipping line 2)
Reboot phone open Safestrap app and Click Reboot To Recovery. If during this process you every get stuck on samsung screen.
Pull battery reboot phone to bootloader (VolDwn+Pwr+Home) load a PB1 rom such as https://www.androidfilehost.com/?fid=24438995911967916 from @muniz_ri
Once you load the rooted PB1 you can unlock the bootloader and follow my post on how I updated at http://forum.xda-developers.com/ver...0-keeproot-t3149784/post67248881#post67248881

Can i not just download the 6.0.1 firmware from sammobile and upgrade through odin, Cause I am concerned i will brick my phone or smth and I am not at home and don't have a laptop with (will have to use a public one). Thanks

Updating directly to PD1 is possible if you can find a tar file, but PD1 is not rootable without the unlocked bootloader which can only be achieved through PB1.

Don't know how far you want to go but just ODIN back to NCG, TowelRoot, install FlashFire and go to muniz_ri's root thread. Check your CID by using phone info app and you may be able to unlock your device if you've got the 15 eMMC chip. Currently the 11 chip is work in progress for unlocking the bootloader....but do as you wish to root...I'm 'ol school....lol

Rooting Samsung Galaxy J3 (2018)

Hi everyone, I hope I am posting this in the correct section, and if not, can an admin move my post to the appropriate place? I am a geek with PC's but mobile is new to me and I would like to root my device which is a Samsung Galaxy J3 (2018) version. I cannot find info here after searching. Here is what I achieved thus far. I downloaded what I think is the firmware file named FirmwareX.Net_J337WVLS2ASC1_J337WOYV2ASC1_PCM_8.0_Full which has my model number SM-J337W and part of build number in the filename. My build number fully is R16NW.J337WVLS2ASC1. The IMEI is 359229091474959.
I downloaded latest odin tool and just about to download TWRP and my model is not in their list and thats where I'm at. Can someone confirm if this is the actual stock firmware rom, and if I am ready to proceed and some steps would be appreciated. I was told by Oneclickroot service that they have a different stock firmware, and just wanted me to pay for something I can probably do on my own, so I'm puzzled by their reply as I had a very hard time finding this firmware which seems to be the closest match. Has anyone here ever rooted this particular device and provide me a sure step by step way to root it? I do have the setting options OEM Unlock and USB Debugging if that helps.

The stock firmware that you downloaded is for your model number but you need to verify that it works with your mobile carrier. If you downloaded the correct firmware for your region and your carrier.
There isn't a TWRP recovery or a known rooting method for your model number. You'll have to try the various universal rooting apps and the various rooting programs for PC and hope of them works.
Or you might can extract the boot.img from the stock firmware that you downloaded then use Magisk on PC to create a modified boot.img then flash that modified boot.img via Odin then reboot the device and install the Magisk root manager app on the device to gain root. If your bootloader is locked, you won't be able to flash the modified boot.img, you'll have to find a method to unlock your bootloader, if one exists for your model number, android version and build number.

Thank you for the reply Droidriven, I thankfully have the option in settings to unlock the bootloader called "OEM Unlock" unlike most other J3's who do not. So basically, you are saying that I can root this device with Magisk with your suggested Magisk method correct? Could you elaborate this method step by step?

I'll explain the "OEM unlock" setting a bit first. The OEM unlock setting does not necessarily unlock your bootloader. On some devices, enabling this setting unlocks bootloader but on most devices it does not actually unlock the bootloader, it only puts the device in a state that the bootloader "can" be unlocked using some form of unlock method after enabling the setting. In these cases, the unlock method would not work without enabling OEM unlock setting before implementing the unlock method.
So, basically, what I'm saying is that even though you have the OEM unlock setting, this does not necessarily mean that your bootloader is unlocked just by toggling this setting, it may still be locked even after toggling the setting. You'll have to verify whether your bootloader is actually unlocked or not. Do some Google searches for:
"Check bootloader status on Samsung devices"
This should give you results to find a method to verify your bootloader status.
Once you have verified that your bootloader is unlocked, you can use the Magisk rooting method. Read the "Boot Image Patching" section in the link below, there are also several other guides all over the internet and videos on YouTube that give instructions on patching your boot.img. As for actually flashing the boot.img, you will be flashing it using Odin. Use 7zip to compress the patched boot.img into a .tar compressed file. When you flash the file using Odin, place .tar file in the AP slot in Odin.

How to unlock Samsung A01

I need some help unlocking the bootloader on my Samsung A01. The instructions say to enable developer mode — basic stuff — and then enable USB debugging and OEM Unlocking. You guessed it: the OEM Unlock option just ain't there. I tried the trick with chaging the date and checking for updates, but it didn't help. Please, can anyone give me some help that will actually fix the problem? I just want to root this damn thing.

Ok then. How do I do it? All the other guides tell me I have to. And how would I install TWRP, which I definitely want to do?
Every guide I look at tells me I have to unlock the bootloader first.

You do NOT need to root your phone's Android to install TWRP - a custom recovery, but you will need to unlock the bootloader. Take note that Android OS has nothing to do with phone's bootloader, that Android OS gets launched by bootloader if device didn't get tampered.

Ok, how do I just root for now? I want Magisk. I'm trying to install it with ADB, but I'm getting Error 21.
Furthermore, how do I unlock the bootloader when the system doesn't want to give me the OEM Unlocking option?

You do NOT need to root your phone's Android before to install Magisk: you typically root Android OS by means of Magisk.
You install Magisk via TWRP what requires an unlocked bootloader. You unlock a phone's bootloader via FASTBOOT tool what requires OEM Unlock option got activated before applying the bootloader-unlock.

So basically until I can use the OEM Unlock option, I can't do a darn thing, can I?
So how do I get it?

I'm going to ask for help on this again. I've been around the forum, I've looked for anything I could find, and I'm still no closer to getting this thing solved.
